Product Details

fastCTDplus Chlorophyll a

Fast response multi-parameter profiler An evolution of the miniCTD, the fastCTDplus multi-parameter profiler is designed to deliver the highest quality CTD and Chlorophyll a observations at fast drop rates.

A conductivity cell designed for optimum flow-through, a fast-response thermistor temperature sensor and 0.01% pressure sensor together with a Fluorometer sensor, all synchronously sampling at up to 32Hz to deliver the highest quality profiles in a lightweight and robust package.

• Multi-parameter profiler - CTD, Salinity, Density, Sound Velocity - Chlorophyll a sensor - Up to 32Hz sampling rate• Optional Bluetooth connectivity • Depth rated to 6,000m • Dedicated PC software

Sampling Modes

Continuous Regular and synchronous data collection from all sensors up to 32Hz.

Profile Data is logged as the instrument descends (or rises), by a user defined pressure difference, through the water column.

Rapid Once the instrument is set to run mode no data is logged until a programmed trigger depth is reached (e.g. 2 meters below the surface).

Completely programmable, the device can be set to record down casts data only, for example, when the probe stops descending and rises by a defined amount logging is stopped.

Communications

The instrument is designed to operate autonomously. Setup and data extraction can be performed using a SubConn connector or via an optional Bluetooth connection with a PC. Multiple profiles can be recorded in the instrument by switching it on then off using the connector switch plug or magnetic switch key for Bluetooth operation. The instrument can also operate in real time or cabled comms.

Bluetooth auto-pairing and discovery make connecting to the instrument simple and robust.
